We analyze the rationalizability of variable-population social-choice functions in a welfaristframework. It is shown that xed-population rationalizability and a weakening ofcongruence together are necessary and suffcient for rational choice, given a plausible dominanceproperty that prevents the...

We suggest an alternative way of analyzing the canonical Bergstrom-Blume-Varian model of non-cooperative voluntary contributions to a public goodthat avoids the proliferation of dimensions as the number of players is in-creased. We exploit this approach to analyze models in which the...

We examine a Stackelberg game where a financially constrainedleader faces competition from a ‘deep pocket’ follower. We analyzethe consequences of this trade-off between a financial and a strategicadvantage for both the design of financial contracts and market structure.We derive conditions...

We study aggregative games in which players’ strategy sets areconvex intervals of the real line and (not necessarily differentiable)payoffs depend only on a player’s own strategy and the sum of allplayers’ strategies. We give sufficient conditions on each player’s payofffunction to...

The paper compares two models of evolution in symmetric twoplayergames with incomplete information. One model postulates thatthe type of a player is fixed, and evolution works within types. Inthe other model type-contingent strategies evolve. In the case of twotypes and two strategies it is...

The paper shows that there is a close connection between (constant)consistent conjectures in a given game and evolutionary stabilityof conjectures. Evolutionarily stable conjectures are consistent andconsistent conjectures are the only interior candidates for evolutionarystability...

This paper examines the interactions between Foreign Direct Investment (FDI), inequality, and growth, both from a theoretical and an empirical point of view. We set up a growth model of a dual economy in which the traditional (agricultural) sector uses a diminishing returns technology, while FDI...

We present the asymptotic properties of double-stage quantile regressionestimators with random regressors, where the first stage is based on quantile regressionswith the same quantile as in the second stage, which ensures robustness of the estimationprocedure. We derive invariance properties...
